Charli XCX Almost Used Ghost’s Voice on Her New Album

Charli XCX has been everywhere lately — between her own hit single “Boom Clap” and collaboration with Iggy Azalea, “Fancy” — and she’s showing no signs of slowing down.

The British singer called in to On Air with Ryan Seacrest on Thursday morning, just after accepting the ALS Ice Bucket Challenge (watch video below), to talk about all of that, plus the MTV Video Music Awards this Sunday, for which she’s up for five awards!

JoJo Wright, who has been filling in for Ryan this week, also had to ask about a supernatural experience Charli had recently at a haunted house.

“I was in Sweden in the countryside doing some recording for my record,” she explains. “There was this weird vibe in this house. It was actually this huge hotel we were staying in, kind of like The Shining. We had done some research and found out that there was a woman who had drowned herself in the lake outside the house when her husband had died in the 1900s. In this documentary, it said that she still lived in the house as a ghost … So we set up a microphone and left it recording all night and at about 5 or 6 a.m., we picked up this noise that was like, ‘Oooohhhhh.’ We pitched it up three octaves and it was a woman’s voice talking … it was cool!”

Although Charli — who just dropped her second single, “Break the Rules” — had planned to use the woman’s voice as a sample for a track on her upcoming album, Sucker, which will be out on October 21, she decided it against it. “People would think I was casting spells on them or something,” she joked.
